Question 1

Which of the following tsunami wave effects might be observed in this image? (Choose all that apply.)

a) (Ridge-based) wave focusing

b) Edge waves

c) Shelf trapping

d) Large, long runups

e) None of the above

The correct answer is D. This is Hilo Bay, Hawaii. This bay is notorious for causing large, long runups thanks to its shallow bottom and funnel shape. Its breakwater wall could cause resonance.
